The automobile side door lock catch mounting structure can effectively improve the dynamic stiffness of a lock catch mounting point so as to improve the door closing sound quality of an automobile door and comprises a lock catch mounting plate assembly and a nut plate assembly, the lock catch mounting plate assembly is fixed to the inner plate face of a C column reinforcing plate, the outer plate face of the C column reinforcing plate is welded to a side wall outer plate, and the nut plate assembly is fixed to the outer plate face of the C column reinforcing plate. And the lock catch is arranged on the outer plate surface of the side wall outer plate. According to the scheme, the lock catch mounting plate assembly is fixed to the C column reinforcing plate, that is, an overall force transmission path is arranged at the mounting point, the dynamic stiffness of the lock catch mounting point can be improved, meanwhile, the lock catch mounting face is formed by attaching and welding three layers of plate bodies, and compared with welding of two layers of plate bodies in the prior art, the strength of the mounting point is high, and the service life of the lock catch mounting plate assembly is prolonged. The stress concentration phenomenon is effectively avoided, the welding spot and metal plate fatigue problem is avoided, and the service life is prolonged.
本发明的目的是提供一种能够有效提升锁扣安装点动刚度，从而提升车门关门声音品质的汽车侧门锁扣安装结构，包括锁扣安装板总成和螺母板总成，锁扣安装板总成固定在C柱加强板的内板面上，C柱加强板的外板面与侧围外板焊接，锁扣安装在侧围外板外板面上。上述方案中，将锁扣安装板总成固定在C柱加强板上，也就是说安装点处有整体传力路径，能够提升锁扣安装点动刚度，同时，锁扣安装面处形成由三层板体贴合焊接而成，相对于现有技术中的两层板体焊接而言，安装点强度高，有效避免应力集中现象，规避焊点与钣金疲劳问题，提高使用寿命。
